Reversible Blockade of Complex I or Inhibition of PKCβ Reduces Activation and Mitochondria Translocation of p66\u3csup\u3eShc\u3c/sup\u3e to Preserve Cardiac Function after Ischemia [PDF]

, 2014
Aim Excess mitochondrial reactive oxygen species (mROS) play a vital role in cardiac ischemia reperfusion (IR) injury. P66Shc, a splice variant of the ShcA adaptor protein family, enhances mROS production by oxidizing reduced cytochrome c to yield H2O2 ...

Modulation of Mitochondrial Bioenergetics in the Isolated Guinea Pig Beating Heart by Potassium and Lidocaine Cardioplegia: Implications for Cardioprotection [PDF]

, 2009
Mitochondria are damaged by cardiac ischemia/reperfusion (I/R) injury but can contribute to cardioprotection. We tested if hyperkalemic cardioplegia (CP) and lidocaine (LID) differently modulate mitochondrial (m) bioenergetics and protect hearts against ...

CARDIAC ISCHEMIA

, 2022
Ischemic heart disease, or ischemic heart disease, is a chronic or acute disorder of the blood supply to the myocardium (the layer of muscle in the heart). This is because the heart does not get enough oxygen. This occurs when arterial blood is given to the heart muscle in limited amounts due to coronary artery injury.

An alternative mitophagy pathway mediated by Rab9 protects the heart against ischemia

Journal of Clinical Investigation, 2019
Energy stress, such as ischemia, induces mitochondrial damage and death in the heart. Degradation of damaged mitochondria by mitophagy is essential for the maintenance of healthy mitochondria and survival.

Myocardial ischemic effects on cardiac electro-mechanical activity [PDF]

arXiv, 2021
In this work, we investigated the effect of varying strength of Hyperkalemia and Hypoxia, in human cardiac tissue with a local ischemic subregion, on the electrical and mechanical activity of healthy and ischemic zones of the cardiac muscle. The Monodomain model in a deforming domain is taken with the addition of mechanical feedback and stretch ...

Monitoring of lung edema by microwave reflectometry during lung ischemia-reperfusion injury in vivo [PDF]

, 2006
It is still unclear whether lung edema can be monitored by microwave reflectometry and whether the measured changes in lung dry matter content (DMC) are accompanied by changes in PaO(2) and in pro-to anti-inflammatory cytokine expression (IFN-gamma and ...

Novel insights into the cardio-protective effects of FGF21 in lean and obese rat hearts [PDF]

, 2014
Aims: Fibroblast growth factor 21 (FGF21) is a hepatic metabolic regulator with pleotropic actions. Its plasma concentrations are increased in obesity and diabetes; states associated with an increased incidence of cardiovascular disease.

Trusting Machine Learning Results from Medical Procedures in the Operating Room [PDF]

AAAI workshop on Trustworthy AI for Healthcare 2022, 2022
Machine learning can be used to analyse physiological data for several purposes. Detection of cerebral ischemia is an achievement that would have high impact on patient care. We attempted to study if collection of continous physiological data from non-invasive monitors, and analysis with machine learning could detect cerebral ischemia in tho different ...
